利用朴实贝叶斯方法求解有关肺炎的问题。肺炎对应有四个特征：发烧、疼痛、咳嗽和血细胞异常，当确定了患肺炎与否时，四个特征条件独立。假设患肺炎与否和四个特征都可表示为Ture和False。 根据pneumonia.tex文件中的数据（500行，每行前4个数对应4个特征变量，第5个数对应患肺炎是否为真，以0表示False，1表示Ture），编写Matlab 程序 maininference.m，从example.txt中读取病人的症状信息（0表示False，1表示True，-1表示not given），并计算对应的患肺炎的可能性。所给的信息按发烧、疼痛、咳嗽、血细胞异常的顺序排列。将计算结果保存在answer.txt中。(Simple Bayesian method to solve the question of pneumonia. Pneumonia corresponding four characteristics: fever, pain, cough and blood cell abnormalities, determine the risk of pneumonia or not, the four characteristics of conditional independence. Assumptions suffering from pneumonia or not and four features can be represented as Ture and False. According to the data pneumonia.tex file (500 lines, each line of the first four numbers corresponding to the four characteristic variables, number 5 corresponds to the risk of pneumonia is true, 0 represents False, said Ture), to write Matlab program maininference. m from example.txt read the information of the patient' s symptoms (0 = False, said True, the-1 indicates not given), and to calculate corresponding to the likelihood of suffering from pneumonia. The information given by the order of fever, pain, cough, blood cell abnormalities. The calculated results is be saved in answer.txt.)

OFDM系统中，发送机的仿真程序，可以运行，已经很好的在本机上运行了，是分析OFDM系统的好的开始(OFDM system, the transmitter of the emulator, you can run, have a good run on this machine is a good start OFDM system analysis)

一个理发店，只有一个理发师，只有n张可供顾客等待理发的椅子，如果没有顾客，则理发师睡觉；如果有一顾客进入理发店发现理发师在睡觉，则把他叫醒，写一个程序协调理发师和顾客之间的关系。(A barber shop, there is only one barber, only the n Zhang barber' s chair waiting for customers, without customers, the barber to sleep if there is a customer into the barber shop barber was found sleeping, others view him wake up, write a program Coordination between barber and customer relations.)

PWM整流器的直接电流控制，采用双闭环控制，调试通过，效果一般(PWM rectifier direct current control, dual-closed-loop control, debug is passed, the effect of general)
